摘　　要：高频放大器是短波发射机的核心,电子管的状态和谐振回路的好坏直接决定了发射机的状态和安全播出的实现。由于各种原因,发射机不能完全依赖自动调谐,往往需要在细调时介入手动调谐。以TBH-522型150 kW发射机为例,从电子管状态为着入点,探究在实际工作中手动调谐的原理和技巧。High frequency amplifier is the core of shortwave transmitter.The state of electron tube and the quality of resonance circuit directly determine the state of transmitter and even the realization of safe broadcasting.Due to various reasons,the transmitter can not completely rely on automatic tuning,manual tuning is often involved in fine tuning.Taking TBH-522150 kW transmitter as an example,this paper explores the principle and skills of manual tuning in practical work from the perspective of tube state.
